REDUCTION SYSTEM.

Specification of Letters Patent.

Patented May 9, 1911.

Application filed June 27, 1910. Serial No. 569,032.

To all whom it may concern;

Be it known that I, ALBERT J. Monmok,

a citizen of the United States, and a resident of the city of New York,borough of Brooklyn, in the county of Kings and State of New York, haveinvented a new and Improved ReductionSystem, of which the folpeopleliving in the vicinity.

lowing is a full, clear, and exact description.

My invention relates to reduction systems used for cooking, reducing andconverting garbage, ofi'al, slaughter house tankage, dead. animals andfish, and materials of various kinds, for the double purpose of riddingcommunities of the various objectionable materials mentioned and ofmaking various products and by-products by workin up the same.

y present invention is assoc1ated.more or less remotely with thatdescribed in my Patent No. 931,457, of August 17, 1909, for a separator,some of the parts in my present invention being similar to partsdescribed in my said patent.

Among the objects which I seek to accomplish by my present invention arethe following: I. To provided for saving greases and oils which mayaccumulate from time to time in the reduction tank under conditionswhere ordinarily these materials might be wasted. II. To prevent undueliberation of noxious gases and vapors to the detriment of health andcomfort of III. To so connect up a number of presses with pressure tanksthat a single pressure tank may be used to fill two presses, therebyenabling the presses to be made smaller than would otherwise benecessary. "IV. To improi e the general efficiency of reduction systemsby improving the construction and action of various parts used inconnection therewith.

Reference is to be had to the accompany ing drawings formin apart ofthis specification, in which similar characters of re't'en once indicatecorresponding parts in both the figures.

Figure 1 is a fragmentary elevation showing my improved reductionsystem; and Fig. 2 is a detail showing one of the presses and thepressure tank immediately connected therewith, this view further showingthe by-pass for dividing the contents of either pressure tank so as tofill two presses of smaller size.

A framework 3 supports conveyor mechanism 4, the latter includingrollers 5, 6. At 7 is a platform associated with the cor.- veyermechanism, and at 8 is a swiveled chute supported by the platform 7 forthe purpose of transferring materials from the lat ter. The parts justenumerated being old and well-known, need no further description. Theframework 3 includes large sup porting beams 9 disposed horizontally.

At 10, 11 are reduction tanks, the tanks being provided with lugs 12which engage the horizontal beams S).

At 13, 1.4 are pressure tanks and below these are the presses 1.5, 16,these presses being substantially of the kind described in my Patent No.931,457, referred to above.

At 17 is a by-pnss connecting the two pressure tanks 13, let directlytogether. This by-pass is controllable by a hand valve 17 (see Fig. 2)and by aid of said valve may be opened and closed at the will of theoperator. Steam pipes are shown at 18, 19 and are fed with live steamfrom a supply pipe 20. The pipes 18, 19 are provided with hand valves21, 22. by aid whereof steam may be thrown into either pipe 18 or 19, orinto both, as desired.'

At 23, 24 are hand valves for opening and closing couununication betweenthe pressure tank 14 and the prcssslti. Steam pipe v 25, 26 arec'ormccted respectively with the bottom of the reduction tank 11 and topof the pressure tank 14, and are controllablc by hand valves 27, 28, thesteam 'bcing supplied to the pipes 536 through the supply pipe 29. Eachpress 1.6 is provided at its bottom with a swinging door 30, this doorcarrying an outlet pipe 3t. The door also carries a "fork 32 in which isa roller 33 running upon a circular track 34: and supporting the weightof the door 30 together with such pressure as may be exerted on saiddoor. A steam pip 35 is connected with the reduction tanks 1.1, 10 bypipes 36, 37. At. 38 is a trap which is also connected with the pipe 35.A pipe 39 leads from the trap 38 to a condenser 10, the latter beingcontrollable by a band valve 41 and being provided with an outlet pipe42. Connected with the bottom of the tra i 38 is a discharge pipe 43which extents downwardly and is provided with a hand valve 44 whereby itmay be opened and closed.

At 45 are platforms and mounted upon the same are railings 46 for theconvenience of the operator.

At 47 is a conveyer belt which runs upon pulleys or rollers 48 and isused more particularly in connection with emptying the presses 15, 16.

At 49 is a pipe leading to a condenser 50, the latter being controllablebyaid of a hand valve 51.

Extending from't-he pipe 49 to the pressure tanks 13, 14-are pipes 52,53. These pipes are provided with hand valves 54, 55.

house tankage, and the 1i 11. For this purposethe hand valve 57 ispreviously closed. -The reduction-tank lo may, it desired, be filled inthe same man ner. The tops of the reduction tanks being closed-tight,steam is now admitted through I the pipes and the materials contained inlthe reduction tanks are thus heated and' cooked. Suppose, now, thatowing to splashing takin place in the reduction tanks 10, 11', cause byaccidental irregularities in heating or lack of homogeneity in the mate-:rial operated upon, it should happen that the portions of solid matterare driven upward throughthe pipes 36, 37. These ortions of solid matterare driven a ong through the pipe andin'to the trap38, It happens thatthe "greases and oils from the material nearly always float on top ofthe materials, and thus being uppermost they are liable to be forcedupward through the pipes 36, 37. If this happens, greases and oils aretaken into the trap 38 along with the solid matter, and as this trap ispartially filled with water 113011 which the greases and oil float, theatter may be readily tapped oil'at any time by aid of the discharge pipe43 and the hand valve 44. All

steam, vapors and gases, including such vapors and gases as are noxiousor possibly oisonous, are free to pass up-' wardly romthe trap 33 andthrough the pipe 39 to the condenser 40 where they.

- are, as far as practicable, condensed and discharged in liquid. "formthrough the outlet pipe 42. In the trap 38 the lower end of the pipe 35normally dips below the level of the liquid. contained therein, thoughthis isnot by any means "necessary. The materials being completelycooked and reduced in the reduction tanks 10, 11, are next trans-,ferred downwardly through the pressure tanks. This. is done by openingthe valves 56, 57a The pressure tanks being'thus filled, the valves 56,57 are closed and steam is adeeaoar mitted throughthepipefliiby aid orthe hand valves 21. If at, any time an overflow takes lace from thepressure tanks 13, 14, or if or any reason greases, solid matter orother portions of the materials operated upon arethr'own upwardlythrough the pipes 52, 53, they pass into the pipe 49 and along withsteam and various vapors and gases are carried to the condenser 50,being rendered, by action of the condenser, as harmless and, as compactas possible. This en- 'ables'these materials to be saved, in so far asthey may be Worth saving. If need be, live" steam may be supplied. tothe pipe 18 and the materials cooked still furtherin the pressuretanks.- The stirring of the materi als,'d ue' to their transfer from thereduction tanks down'int-o the pressure tanks, frequently places them ina'condition to be cooked further by the application of fresh steam.: Theprocess being practicallyfin ished, the next step is to run theconverted materials from the pressure tanks 13, 14 into the presses 15,16. To do this the valves "56, 57 .aremclosed, and the valvesi23, -24 ofeither of'the presses are next opened. Steam being now admittedthroughthepipe 26, the materials are forced downward by steam pressure,so as to fill one ofthe presses. The by-pass 17 being opened byaid of,the valve 17 (se*e Fig. 2) a portion of the, materials is" forcedthrough 'the'pipes into the opposite'pressure tank'if this tank happensto be otherwise empty or happens to be sp'acious enough to receive thematerial.

Under ordinary circumstances, if the apparatus be used in connectionwith ,full

charges of the material, each charge when thoroughly cooked and reducedis just about sufl'icient to fill the two presses. The. pres-' suretanks 13, 14 are emptied alternately" and if there be a large numberofthese tanks they are arranged in pairs, the two tanks of I each pairbeing alternated in their action of discharging into the two presses.Any umber of the pressure tanks 13, 14 maybe sed simultaneously up tothe moment of discharging their contents into the press,|but

in discharging their contents the'pres ure tanks are operated one at atime.

In some instances I rials into only one .o 10, Y11 and when thereduction is com lete,

refer to fill the niate: l the reduction t nks to transfer thesematerials straight d wnward into the pressure tank below and corresponding to the reduction tank thus lsed.

The difference in size'of a reduction ank and its corresponding pressuretank represents theapproximate shrinkage ofth material, due to its.cookingand to variouslosses which always take place during thisoperation. Whereonly one: of the cooking tanks 13 is fullorapproxiinately full {of the reduced material, there is economy inusing both-ofthe presses 15, 16, and this done by aid of the by-pass 17,as above described. That is to say, by using one pressure tank 13 or 14and filling the two presses 15, 16, the work is done as rapidly as wouldbe the case if the pressure tank in questionwere used with a singlepress of larger capacity. It is obvious that if a single pressure tank(13 or 14:) can thus be used with both of the presses'15 and 16, andthese presses can consequently be made smaller than would otherwise benecessary-to wit, just half the capacity-the s stem as a whole is cheap-.ened by the di erence in thecost of large and small resses, and asthese presses are usually quite expensive, thesaving is considerable.Moreover, it frequently happens that in plants of this kind there is ascarcity of room and especially of room extending vert-ically upward. Byhaving the presses 15, '16 comparatively small, as above described, theavailable space is conserved in every sense, and even the building inwhich the plant is located may, if desired, be rendered slightlyloWer-other things being equal0wing-to the reduction in size of thepresses. The materials being forced downwardly into the presses, theaction inside of the presses, and subsequently to their filling, issubstantially the same as that described in my patent above mentioned..The materials and products extracted therefrom are removed from thepresses in the'manner already known in this art and described in myexisting patent.

While I show the various reduction and pressure tanks as cylindrical, itwill be understood that I do not limit myself thereby,

terials mentioned, around large cities where they accumulate and mustnecessarily be dis;

posed of in some suitable manner. Byaid of the system above describedthe materials may be disposed of at considerable advantage, the variousproducts and by-products being oftentimes of considerable value.

Having'thus described my invention, 1'

claim as new and desire to secure by Let'- tersr Patent a 1. Thecombination ofva plurality of pressure tanks, a bypass connecting thesame together, a separate press connected with each of said pressuretanks, and means for applying pressure to materials contained within oneof said pressure tanks for the purpose of causing a portion of saidmaterials to pass across from one pressure tank to another in order tofillall of the presses. 2. In a reduction system, the combination of aplurality of pressure tanks, a plurality of presses each connected withone of said pressure tanks, valves dis osed between said pressure tanks,and a y-pass extending from one of said )ressure tanks to another. Intestimony w ereof I have signed my name to this specification in thepresence of two subscribing witnesses.
